, SPECIFICATION forming part of Letters Patent No. 358,773, dated March 1I 1887.

Application filed .Tanuary 22, 1887. Serial No. 225,176. (No model.) Patented in Norway April l9,'1886, No. (l5.

To all whom it may concern.-

Be it known that I, OLE FLAGSTAD, manufacturer, a citizen ofHamar, residing at Hamar, in the Kingdom of Norway, have invented certain new and useful Improvements in Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Referring to the dra-wings, Figure lis a horizontal section of a window frame and sash embodying my improvements. Fig. 2 is a like view of a portion thereof, showing a slight modification in the construction, the sash in Fig. l being shown about half-open, and in Fig. 2 but slightly open. Fig. 3 is a vertical section of the frame and sash, thelatter being closed; and Figs. 4 and 5 are detail views.

This invention consists in a novel construetion of window sash and frames, substantially as hereinafter fully described, and as set forth in the claims.

In the accompanying drawings, A indicates the window casing or sash frame that has in its head and sill Al A2 a groove, a,- and B B indicate the two window-sashes provided with blocks or pins b b, projecting therefrom and into the grooves a, thus forming a sliding connection for each sash with the fraaie.

If desired, the sash may be pivotally connected with the groove, so as to form a pivotal sliding connection between the sash and frame, for purposes hereinafter described, in which case I provide the journals 112112 with a roller, b4, Fig. 3, to reduce the friction and facilitate the moving of the sash in opening and closing the window.

To exclude water and snow from and the formation of ice in the grooves a of the frame A, I provide each sash on opposite sides ofthe lower cross-bars, B', with weather-strips b b.

The vertical bars B2 that slide along the sashframe are provided with a bead, b2, that lies or ts into a corresponding groove, a", formed in the inner face of the sides of the casing ory frame A, so that when the window is closed the air will be effectually excluded from the room.

The two sashes are hinged together along their vertical bars IB3 in any suitable or preferred manner, and are provided with locking devices to lock the same together or to the.

frame A, when the sashes arein their closed position. In Fig. 1 I have shown the bars B3 provided with hingeknuckles C, projecting from suitable straps screwed to the adjacent sash-bars and pivotally connected by suitable pintles, O.

A single pintle or rod may be employed, eX- tending the full length of the sash, and carrying at each end a locking-hook, c, adapted to engagey a staple or pin, a, projecting from the head and sill of the frame or casing A, or from the lintel and sill of the window, as shown in dotted lines in Fig. l, the pintle-rod G being provided with a handle, c', to rotate the same and also to move the sash in opening and closing the windows; or, if desired, the pintle-rod C may in a well-known manner be made in two sections adapted to move up and down, respectively, into suitable sockets in the head and sill of the frame to lock the sash closed o when the handle-lever is manipulated.

The pintle-rod or the sectional pintle-rod or the independent hinge pintles may, if desired, be constructed so as to be removed from the hinge-knuckles, thereby affording means to swing the sash into the room to afford ready access to the glass for purposes of cleaning when said sashes are connected by a pivotal sliding connection with the frame A, as above mentioned.

The window-frame may also have a central vertical stay or post, I), dividing the frame vertically into two equal parts, as shown in Fig. 2;v and arod, E, may be pivoted to one of the vertical sash-bars B3, by means of which the sash may be manipulated in opening and closing the same, said rod serving, also, as a means for locking the sash closed by engaging pins d d, secured to the central stay or post, D, as shown in Figs. 2 and 3. v

The rod E may terminate in an eye, e, and the post D may he provided with a hook, d', so that the sash may be locked in a partlyopened position, sufficiently so to thoroughly ventilate a room, yet not sufficiently for a child to pass through the opening. This arrangement also prevents small children from tampering with the window, and when partly ICO opened the rod E may be more securely locked by means of a spring, e', secured to the post D, as shown in Fig. 5. In this construction the post will be provided with suitable recesses, d2, for the reception of the hinge-knuckles, as shown in dotted lines in Fig. 2.

In order to form a practically air-tight joint between the two hinged sash-bars B3 B3, I preferably form on the one a bead, b5, adapted to t into a corresponding groove, b, :in the adjacent face of the other vertical sash-bar, as shown in Figs. 1 and 2. To provide means for removing the sashes from their frames, I form in the sill of the frame A two recesses, a, of greater depth than the grooves (t, in which are iitted removable blocks ai. It will be seen that when lthese blocks are removed from their recesses or slots, and the sashes are moved to bring their pins opposite thereto by pushing the sashes outwardly to move the lower pin or journal into the recess, the upper pin will be disengaged from the groove a in thehead of the frame, and the sashes can then be bodily removed. Instead of this arrangement, the inner or the outer wall of the grooves ct may be formed by means of a detachable bead, as is the case in the usual construction of windows.

The described motion of the sash may, if desired, be reversed-that is to say, the sash may be arranged to move in vertical grooves in theframe sides-suitable means being employed to lock the same in position. The described construction of window presents various advantages over those heretofore in use, and especially over that class of windows in which the sashes slide vertically one over the other. These advantages may be enumerated as follows: greater Ventilating capacity, as

'nearly the entire window-easing space may be utilized for this purpose, as it is obvious that after the sashes have been fully opened and brought together they may be left in this po-` `sition or pushed to one or the other side of the casing or frame A.

Ready access is had to both sides of the glass G without removing the sash for purposes of cleaning. A more perfect closure can be had, and one which excludes almost absolutely all air from the room. In their open position they are not readily displaced even by the strongest wind; hence thereis no dan-v ger of their slamming, as is the case with the ordinary wing-hinged windows. They act as air-deiiectors to deflect the air into the room, no matter from which side of the window the currents may come and `whether the sashes stand centrally of the frame or on one or the other side thereof, since they can readily be moved from the center to one or the other side of the frame. The facility of opening and closing the window even when there is a tight fit between the sash and the frame is increased by reason of the great leverage afforded, and when a central post is employed the window may be partially opened for purposes of ventilation without danger of a child falling out.

Having now particularly described my invention, what I claim isl. The combination', with a sash-frame provided with diametrically opposite guidegrooves, of a pair of sashes hingedtogether to fold one upon the other and unfold in opening and closing the window, and provided with projections on opposite corners fitting and sliding in said guide-grooves in moving the sash to fold or unfold, substantially as and for the purpose specified.

2. The combination, with a sash-frame provided with diametrically opposite guidegrooves, of a pair of sashes hinged together to fold one upon the other and unfold in opening or closing the window, a removable hinge; pintle for the hinges thereof, and a journal projecting from the sash into the guidegroove to form a-sliding pivotal connection, whereby on removal of the hinge-pintle either -sash can be swung into or out of the room,

and moved from one side of the frame to the other, substantially as and for the purpose specified.

3. The combination, with a sash-frame, of a pair of sashes hinged together to fold one upon the other and unfold in opening and closing the window, a sliding connection between the sash and frame, and a lock to lock the sash in a partially-open position, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

OLE FLAGS'IAD.
